* Ever heard the song [[http://www.youtube.com/watch?v=esYm9q-bi4w&fmt=18 Ai no Uta]]? The one that sounds "cute" and "calming"? Yeah...that's only [[LyricalDissonance if you don't know what the words actually mean]]. You can hear a fairly literal English cover [[http://www.youtube.com/watch?v=7yKHYupriRw&feature=related here]]. The lyrics are a complete PlayerPunch to the gut, especially the last line, [[spoiler: "...but we won't ask you to love us."]]
** The song is just more heartbreaking/heartwarming as you analyze it. The Pikmin are doing this all because they care so much about Olimar and want to help him. So badly that they'll put themselves into danger, fully knowing that some of them will die, ''just to help Olimar''. And they want nothing in return, not even Olimar's ''love''. And they even strive to try harder. The Pikmin are the most selfless creatures ever, and they don't even ask for recognition.
** The counterpart to the above song, [[http://www.youtube.com/watch?v=-T-QHAkDf-8 Namida Ga Afureta]], is just as heartbreaking. Translated to 'Tears Overflowing', the song is in Olimar's point of view, who regretted that he could never truly express his gratitude and love to the Pikmin [[spoiler: he owed his rescue to at the end of the first game]].
*** Of course, given that in the sequel he really had all the time in the world, this leads to [[FridgeBrilliance Fridge]] [[CrowningMomentOfHeartwarming Heartwarming]] for Pikmin 2.
* If you let yourself get attached to them, a single Pikmin death can be this.
* When a Pikmin dies its soul floats away with a depressing half moan half wail.
* Did you forget any Pikmin out in the field at the end of the day? If so, you're treated to cutscene of the left behind Pikmin being chased and eaten by the area's predators. Or even more heartbreaking, the remaining Pikmin desperately trying to make it back to the ship as it takes off without them... and it becomes worse in the third game, where they are given unique cries in panic when this happens.
* Bulbmin. Sure, they're part nightmare fuel, but think about it. You kill their leader and then they turn to you. You use them along with your trusted allies, and they get you out of tight spots...then, you abandon them when you leave, and they just look up at you and frantically swarm the geyser...what happens to them?
* Pikmin Extinction. This occurs when you lose every single Pikmin you have and having none left in the Onion. Hundreds of little plant creatures... and you're responsible for them all dying. Feel bad yet? Olimar certainly does:
-->"[[TotalPartyKill The Pikmin have all perished because of my own carelessness]]. [[MyGodWhatHaveIDone I am an utter disgrace as a leader]]... How can I continue to collect parts without them? Still the Onions join me in low orbit, as if this Pikmin extinction had never happened. [[PlayerPunch I shan't sleep tonight...]]"
* The [[http://www.youtube.com/watch?v=gHtrXPmStbU credits]] to the first Pikmin, arguably.
** The third game's [[http://www.youtube.com/watch?v=aFsSUWlBLbk credits]] could also qualify, especially for one who grew up with the first two Pikmin games.
* Some of [[http://www.pikminwiki.com/Olimar%27s_Voyage_Log Olimar's Voyage Logs]].
--> "I wonder if I shall ever be able to escape from this world. How much suffering must I endure before I can finally see my family back home again? Still.... When my heart grows too heavy, I take comfort in my efforts. I will get home...or I will expire trying."
** Day 28:
--> "I suppose I have done well to get by without much motivation. I have made it this far without any hope."
** If you have less than 25 parts [[GameOver by day 30]], Olimar manages one sentence:
--> "I am so very tired."
* If you lose a large amount of Pikmin in 3, Captain Charlie may make a diary where he holds a moment of silence, then says that watching a soldier perish is something that you'll never get used to, but you have to carry on anyway.
* The GoldenEnding of the first Pikmin can be pretty emotional, watching Olimar bid the Pikmin farewell as they look on sadly.
* Think Olimar gaining control of the Pikmin ruined their lives? [[https://www.youtube.com/watch?v=Kfq2wTa5Dl0 This fan video]] might make you think again. [[spoiler:It begins with a large crowd of Pikmin together simply relaxing, messing around, or even falling in love. Then a mass of Bulborbs attacks and drives them away. [[FromBadToWorse It only goes downhill from there.]] Sheargrubs eat some, a group of four is cut in half when a Snitchbug carries two away, and it's cut down to only a pair of Pikmin. Music begins playing as they finally find nectar, implying that things might start going another direction... before a Burrowing Snagret eats one of them. The last Pikmin runs in panic, finally resting to look up at the night sky all alone and think back about all of the previous tragedies. Wait, night? ''When the creatures get more active?'' It finds itself surrounded by a number of predators, before the camera zooms out to reveal a certain crashed ship. It's very slightly implied that the race somehow survived to make the Onions Olimar would later find and use to help rebuild them, but still, '''''[[DownerEnding damn]]'''''.]]
* After spending the whole second game with the JerkWithAHeartOfGold Hocotate ship, it was pretty jarring to see it [[spoiler: broken and silent in the ground in Pikmin 3. One can only hope they eventually dug it out and repaired it.]]
* Brittany's notes on the Tremendous Sniffer (a pear). She at first compares the texture to her Aunt Bea, and likens the fruit's shape to that of her aunt's nose. After a brief tangent [[ItMakesSenseInContext about her aunt's nose]]...
--> '''Brittany''': I miss my aunt. I want to go home.
* Let's talk about Emperor Bulblax for a bit. He's the final boss of the first Pikmin game, and any attempts to throw troops at him result in them harmlessly bouncing off. So how do you kill him? Well, there are a bunch of bomb rocks, and a yellow flower nearby... If you hadn't guessed yet, the way to beat him is giving your yellow Pikmin bomb rocks, and then throwing them at the Bulblax to eat. It's not a very sad moment if you don't care about your Pikmin, but if you do, it's unbearable. [[spoiler:It is possible for the Yellow Pikmin to throw the bomb rock before the Bulblax can eat them, but it requires very good timing.]]
